If I ever need a
travel agent...I'm contacting you! You really go above and beyond for your clients!
I use a regular binder with 8.5x11 pages for the actual planning, then I have a 4x6 for the trip so that I can throw it in a backpack or purse.
For the 4x6, I use cardstock to make mine and either use chip board or laminate the front and back page, then I laminate the section dividiers, and have everything spiral bound. Here is a link to one that I fell in love with and decided to make something similar:

I also made pages like Natalie's (Donatalie) for photo pass information and daily planning pages like Kathy's (Mickeysbestgirl)
I have sections for:
Travel - Packing List/Car/Flight/Hotel Information
Financial - Pre and Post Budget
Park Planning Pages
Special Events - i.e. Bibbity Boppity Boo Makeover, etc.
Photo Pass
Journal - Daily Favorites/Daily Highlights
Miscellaneous - Post card list, shopping/gift list
